Myntra.com — T Shirt received short in No.

I have ordered 5 T shirt from Myntra.com and on 27th/May the packet was received at 4.05 Pm and it was opened at 4.14 Pm .
The packet only contain 2 T shirt and the complaint of the same was lodged on 4.15 pm .
Since then i have following the company now and then and they are not looking at my complaint and have closed the same informing lack of evidence .
This is completely unacceptable and i have been cheated by the company .
None of the senior is ready to attend the call despite holding call for several minutes .
